From b0f38452ff73da7e9e0ddc68cd5c6b93c897ca0d Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Fri, 19 Mar 2010 17:16:42 +0100 Subject: netfilter: xtables: change xt_match.checkentry return type Restore function signatures from bool to int so that we can report memory allocation failures or similar using -ENOMEM rather than always having to pass -EINVAL back. This semantic patch may not be too precise (checking for functions that use xt_mtchk_param rather than functions referenced by xt_match.checkentry), but reviewed, it produced the intended result. // @@ type bool;
